Transport plan calls for Kangaroo Is freight corridor

A new transport plan says a freight corridor is needed on Kangaroo Island to cope with the expansion of the timber industry.

The draft strategy has been released for public feedback.

Strategy chairman Malcolm Boxall says it will cost up to $185 million to improve port facilities at Ballast Head and roads.

"By the time it's in full operation in 10 years' time there'll be 600,000 tonnes of woodchips per year to be moved. The last leg to the port facility is only a dirt road and there's no way it will handle that amount of traffic," he said.
